Step 3. Installing the Rotor/Pulley Assembly (8)
Note: Do not mar the rotor/pulley or hub/arma-
ture drive surfaces. Prevent any oil or grease
from contaminating the friction surfaces.
A. Install the rotor/pulley assembly (8) onto the
compressor (10). If the rotor/pulley does not
slide easily, check the compressor nose for
nicks or burrs and remove them. If the
rotor/pulley still does not slide on easily, rock
the rotor/pulley back and forth by hand until it
slides completely onto the compressor (10).
B. Make sure there is no interference between
the field assembly (12) or leadwires and the
rotor/pulley (8).
C. With snap ring pliers, spread the rotor/pulley
snap ring (9) and insert it into the groove on
the compressor nose per Figure 1. To assure
assembly retention, the ring bevel must face
away from the compressor.
(See Figures 3 and 4)
D. Verify that the snap ring is fully seated in the
groove around the circumference to assure
assembly retention. (See Figure 4)
Step 4. Installing the Unidamp ® Hub/Armature
Assembly (3)
Note: Do not insert screwdrivers between the
hub/armature and the rotor/pulley to remove
hub/armature as they will damage the clutch.
A. Slide the Unidamp Armature assembly (3) onto
the compressor shaft (13).
B. Set the rotor/pulley (1) to hub/armature (2)
airgap to
.018 to .030 inches by adding or
removing shims (4). Measure using a feeler
gauge at 3 locations 120 degrees apart.
(See Figure 1) Should a used clutch be
installed, set the rotor/pulley (1) to hub/
armature (2) airgap to .013 to .025 inches.
C. Install washer (5) and retainer bolt (6).
Torque to 155 in. lb.
Note: As the shims may compress when
retainer bolt (6) is tightened, recheck airgap at
three rivet locations (7).
Step 5. Clutch Assembly Check
A. Rotate the clutch and check for rubbing or
interference.
B. Reinstall belts per manufacturer's service
manual. Do not over tighten.
C. Recheck airgap at 3 or 4 points for clutch
rubbing. Airgap to be
.018 to .030 inches.
D. I
mportant: Burnish as follows. Run the clutch
at 2500 to 3000 RPM. Cycle the clutch ON
and OFF at a rate of 10 to 15 times per
minute for a total of 50 cycles minimum. This
will assist in bringing the clutch up to operat-
ing torque capacity.
Cycle the clutch using the
controls inside the car or electrical system
damage could result.
